Abstract:Recently, physical quantum-bits (Qubits) have achieved a remarkable operational fidelity >99.9% and a coherence time ranging from milliseconds to seconds with classic quantum controller (300K). Quantum error correction has also been successfully demonstrated. This paves the way towards a scalable, error-corrected quantum computer. However, the manipulation and sensing of large-scale Qubit array with high fidelity are still facing many challenges of error management. One error mechanism is the dephasing of the coherent superposition states of Qubits, induced by the phase noise (PN) of microwave
